FIELD OF THE INVENTION

The present invention relates to container sacks, and more specifically to an impermeable bag for holding articles.

BACKGROUND OF THE INVENTION

Container sacks such as bags are typically used for carrying articles such as cell phones, cameras and the like. However, a problem arises when a user is carrying the articles in a bag while performing outdoor water activities, such as kayaking, canoeing, rafting, water sports, and the like. While performing the outdoor water activities, water may seep through the bag and cause damage to sensitive items that the user may be carrying. Examples of the sensitive items include cell phones, digital cameras, Global Positioning System (GPS) equipment, maps, documents and currency notes.

Waterproof bags are available for carrying the sensitive items while the user is performing the outdoor water activities. The waterproof bags require suitable sealing mechanisms to prevent the water from entering into the waterproof bags, so that the said sensitive items may not be damaged. Several sealing mechanisms are typically available to seal the waterproof bags. One sealing mechanism involves folding a waterproof bag several times, thereby reducing storage space that is required for storing the items. Another sealing mechanism involves a sliding-fastening element present on the waterproof bag for closing and opening the waterproof bag. The sliding-fastening element includes a grasping member that facilitates the user in operating the sealing mechanism. The grasping member is attached to the sliding-fastening element through a knob. While performing a sliding motion of the knob on the sliding-fastening element, the grasping member may break, thereby causing inconvenience to the user in opening or closing the waterproof bag. Moreover, the waterproof bags are often inconvenient to hold when the user is performing the outdoor water activities.

Accordingly, there is a need for a waterproof bag for holding articles dry while performing outdoor water activities. Further, there is need for a sealing mechanism in the waterproof bag that is convenient to use for opening or closing the waterproof bag, and simultaneously, prevents water from seeping into the waterproof bag. Moreover, there is need for a waterproof bag that may be conveniently carried by the user while performing the outdoor water activities.
